Dieses Reagenz ist als Gegenfärbung bei der Immunhistochemie und Insitu-Hybridisierung bestimmt.Dieses Reagenz ist für die Verwendung in der In-vitro-Diagnostik bestimmt. de In general, immunohistochemistry (IHC) allows the visualization of antigens via the sequential application of a specific antibody (primary antibody) to the antigen, a secondary antibody (link antibody) to the primary antibody, an enzyme complex and a chromogenic substrate with interposed washing steps. The enzymatic activation of the chromogen results in a visible reaction product at the antigen site.Similarly, in situ hybridization (ISH) staining allows the visualization of target DNA or RNA sequences via the sequential hybridization of a labeled DNA or RNA probe to the target, a primary antibody against the labeled probe, and a secondary antibody to the primary antibody, an enzyme complex and a chromogenic substrate with interposed washing steps. The enzymatic activation of the chromogen results in a visible reaction product at the target site.For both applications, at the end of incubation step, the instrument washes the slides to stop the reaction and remove unbound material. The specimen may then be counterstained with Hematoxylin II solution which is applied to the slide and mixed over the entire specimen area. Hematoxylin II stains nuclei blue through the binding of a mordant dye complex to nucleic acids and histone proteins of the heterochromatin. Coverslip may then be applied to the specimen. Results are interpreted using a light microscope and aid in the differential diagnosis of pathophysiological processes, which may or may not be associated with a particular antigen or nucleic acid target. en
